AND MEANS FOR IVARUTG :MATE

Original application filed April 18, 1923, Serial No. 632,815. Divided and 'thsapplcation filedA April 23,

V)The present invention relates generally to devices or mechanisms for marking and is more specifically directe-d to improvements in such mechanisms, which are especially designed for applyinsf trade-mai.' is, tradenames and other identifying vmedia to piece or sheet mater'al, such as paper, fabrics and the like. e

As is well known, it is va common practice for manufacturers of wall papers, fabricsV and the like to applyto the goods of their production trade-marks, trade-naines or other insignia to indicate quality, yardage and the like. Such identifying media are usually .applied to ther sel ",e of the material by means of decalcoman a transfers and various forms of imprints, as well as' by'eml'iossingr. '.lhe mechanisms for applying the afore said media on the material are `more or less complicated in construction and operation, and generally take the form of'a unit which is independent of other mechanisms or ma-l chines used in the production of the material, so that to a large extent the application of the manufacturers trade-mark, trade name, or the like calls for a separate operation which adds to the cost of production of the material.

' For example, assuming that it is the practice of the manufacturer to apply his particu# lar marking' to fabrics in the piece, after they have been finished, the material, following;

the finishing' operation, must be wound upon Y a suitable frame or support for themarking operation, followingwhich it is again woundI on a carrier from which it is transferred to the bolt boards or the like. Ob viously, the several rewinding` operations and transporta-tion of the material tothe maaking` mechanism materially increases the operations necessary to obtain the marketable product with a consequent added cost to the manufacturer and consumer.

rlhe general object of the present invention is to eliminate the additional cost of marking the material, which results Vfrom the methods now employed, and so simplify the mechanism and method of markingthe material that the marking` may be acc mplished. simultaneously With,or as a part of, an essential operation or step in the produc-tion of the material. Manifestly, the cost of marking will therefore be a negligible item in the production of the materialfor the market,

and at the same time the capacity o1 a iven production unit will be increased.

More specifically, it is the object of my invention,L toV provide a simple method and means for applying any desired markings to paper, fabrics and similar material, which may be employed in conjunction with any machine used in the production of the material, where the stage of production may permit of the use of said means. f

This method or means for applying the desired markings is preferablyv used in conjunction with mechanism. described and more particularly claimed in my Patent No.l 1,630,27l, issued May 3l, 1927, of which the present application is a division.

ln marking', as heretofore known, it has been customary to employ heat as an agent for effecting' the marking, either by decalcomania transfer or otherwise, and in my present invention, Iliave devised a method and means in which the heat generated in or radiatedby the machine, such as a calender, in which the production operation is taking;

' place, is utilized to that end, thereby further.

overcoming' the objections to the marking mechanisms as now constituted.4 Y

Other objects andy advantages flowing from my invention will present themselves as the description proceeds, and I would have it understood that I reserve unto myself all rights tothe full range of equivalents, both in strueture and uses, to which I may be entitled un der my present invention in itsbroadest aspect. Y

For the purposesof the present disclosure, l have elected to illustrate and describe one form of means whereby my method may be carried out. lt Will. be obvious, however, that the means forA practising my method of marking` may take other forms to moet special requirementsofuse without departing from the spirit and scope of my invention, as defined by the appended claims.

ln the drawings:

Fig. l is an elevation, partly in section, ofk

a preferred form of mechanism as used in conjunction with a unit of. a manufacturing equipment, whereby my method may be prae tiscd or carried out;

2 isa ton plan view of the structure shown in the left hand half of Fig. l

Fig. 3 is view similar to 2 of the structure shownin the rieht hand halt ot Fig. 1; and

Fig. lis a plan view section ot paper, vfabh ric or the like, the selvage ot which has been marked by practising iny improved iiiethod.

Referring now to the drawings in detail, iii which like characters ot reference are eniployed lo designate siinilar parts throughout the several views, 7 indicates a reel or spool upon which is wound a relatively narrow ribbon or tape 8 of paper, fabric or other suitable inatei'ial having;` equidistantly spaced laterally extending tabs or projections 9 along one edge thereof. These tabs or projecting portions may be yperforated in any suitable inanner, as shown at 10, to torni a stencil et any desired trade-naine, or other insignia which is to be affixed to the material to be marked. lf desired, in lieu of the aforesaid stencil, said tabs or projections 9 inay carry deeal'eoniania transfers or mayv be otherwise formed to provide a die or other inediuin tor carrying out the objects of this invention in tlieinanner hereinafter described.

The reel or spool 7 inay be oi any diameter to carry the requisite supply oi tape or ribbon for any given operation, or for a nuiiiber ot operations as the case may beu This reel or spool 7 is supported or mounted on a stub shat't 11, keyed or splined thereto so as to rotate tlieiowitli,tl1e' ends ot said shaft prot-ruding beyond the plane ofthe sides ot said reel. The said shaft 11 is removably jouinaled in split bearings supported from the opposite walls 12 and 12a, respectively, of the protective cage or housing' 13 which is preferablyA t'orined' of sheet metal or any other inaterial suitable to the purpose, andot the contigui-ation shown. The splitbearing' aforesaid comprises a fined lower half 111, havingei;- tensions 15 and 16, to the lornier oit which the upper half ot' the bearing 17 hinged or pivotally connected, as shown at 18.

From this construction, it will be observed that the shaft 11 carrying; the reel 7 inay be positioned within or removed froin the bearings with facility and despatch, the shaft being locked in functioning position in the bearings by ineans ot the wine; nuts 18 in. threaded en njagfeinent with the studs 19 which are pivotally connected to' the extension 16 oin4 the bracket 1li, as shown at 20. for entering; the open end elongated slots 21 iu the extension 22 ot the upper halt bearing,` 17.

The ribbon or tape 8, which carries the stencil or other inediuni, `by which the inalcrial to be operated upon inay be inarked, as it is univound trein the reel or spool 7, traverses an elongated trough or chute-like guiden way 23, which is a continuation ot' the' base and sides of the housing 13, the tape or ribbon 8 as it leaves the spool, passing' beneath the roll 241 journaled in the upwardly directed parallel. Hang-es 25, which 'torni the sides of said guideway 23.

ln the present showing of i'ny invention, l have elected to illustrate the saine as used in connection with a oalend ringl inaehine, such 'as is eoniinonly employed in finishing fabric and other materials, the calender rolls, the upper one of which is usually a heat roll being` indicated by the reference nninerals 25 and 27, respectiT-Jely. rthe housing 13 with it elitendinr guideway 23 'toi' the tape or i'ibbfjin 8 is oca-ted in iront ol', or in advance ol.: the iiiachine rolls 2G and 27.

ils also described in iny 'co-pendingl cation aforesaid, the housing 13 with its extending' ,gruideway .iay be pivotally mounted on a bracket 28,'siidably inounted on a rod 29,. positioned transversely et the calendering' niaoliiiie, the said rod or bar 29 being` connect -d to the ealendering` inachine traine ineinbers 3() ior adjustment longitudinally thereof. The bracket 28 inay .be a casting', or inay be formed o1' any suitable "iaterial, and is preferably provided with a bore conorining` to the contour of the rod or bar 2S),

and ot dimensions to perniit of the inoveinent oit said bracket longitudinally ot said rod or bar, or in. other words, transversely oit the ealenderiiig inachine 'i' aine, the sai-d bracket being; locked in posicion ot adiustineiit by 1, o1 'n *tl ,i cnij i. v Dl Tl nf; vr o l inemis oi rie so Iscrei. o ie a owsaic pivotal connection between the bracket 28 d and the housing 13 is obtained by forming; an annular pin or prot-uberanee 32 on the ripper surtace ot the bracket 28, whichA is adapted to enter a coinpleinental recess 33 in the boss or block 84:, lined to the base of the housing` 13 by ineens oi. rivets or the like 35. By this method of' connection between bracket and the boss or block Se, it will beV observed that applithe housing; 13, with its'etteridingY guideway 23, will be capable of oscillatory noveinent with relation to the bracket 28, hereinafter explained.

The niateri al 35120 be operated upon by the calender rolls 25 and 27, respectively, trav erses the usuall guide or tension rolls 37, 38 and 39 and passesbetween said calender rolls 26 and 27, beine; carried over a rod or bar 45t-0, positioned transversely ot the niacliiiie traine and between the roll 39 and calender rolls 26 and 27. This rod or bar 1-0 forms a table, the top of which is in the plane oilthe periphery of the adjacent guide or tension ioll 39, so that that portion ot the material 3G which is supported by said roll 39 and the table 40 is in ay substr; tially horizontal plane. i'

lt will be observed that the terininus of the guideway 23, when the housing 131s mounted relative to the rolls 26' and .27, as just described, is at a point approximately between the roll 39 and the table 11G. Positioned on the inside ot the Iguideway 23, adjacent to its terminus and on the median line thereof, is a dependent lug' or stop 41 which is adapted to contact with, or bear llt) table vis in close contact with the material i 36 and enters between the calendering rolls 23 and 27 therewith.

The tapeS, as it isunwound from the spool or reel 7 passes under the roll 24, as aforesaid, and is guided in its movement through the guideway 23 by means of fingers 42, which are supported by transverse rods 43a connected to the edges of the guideway 23. These fingers 42 project downwardly into the guideway and contact with the edge of the tape or ribbon 3, from which the tabs 9 project. v The tape 8 in traversing the guideway 23 is thus at all times, during the feeding operation, maintained in position to insure registration of the tabs or projections 9 thereof with the sclvage edge of the fabric 36, the pressure of the turned-up end portions 42 of the lingers 42, in a downward direction, being so adjusted as to permit lthe tabs or rprojec-Y tions 9 of the tape 3 to ride beneath said fingers without injury thereto.

As the material 36 is drawn beneath the calendering rolls 26 and 27, the vibration of the machine and the slight lateral variations in the path of movement of the material are provided for by the aforesaid pivoted connection between the boss or block 34 and the pin 32 of the bracket 28. rlhis pivotal connection permits the spring 43 fixed to the bracket as at 44 to exert sufficient lateral pressure against the pin 45 dependent from the underside of the guideway 23 to maintain the lug or stop 41 continuously in contact with the adjacent edge of the material 36.

lt will be noted that a portion of the guideway, adjacent to its terminus, overlies the material 36 in its passage from the roll 39 to the table 40. T o prevent undue pressure of such portion of the guideway 23 on the material 36, by reason of the weight of the parts supported by the boss or block 34, there may be provided a Counter-balancing weight 46 threaded on a screw 47 extending from the rearv of the housing 13. By this means the position of the guidevvay, with relation to the material 36, may be accurately maintained during the entire period of the marking operation.

As the tape 8 is drawn beneath the calender-ing rolls 26 and 27, the tabs or projections il of said tape being in contact with the edge of the selvag'e of the material 36, it will be obvious that the heat of the roll 26 combined with the pressure exerted by said calender rolls on the said tabs and the material will effect a transfer of the indicia, or other marking provided on the tab or projection 9 of the tape 8 tothe material. lFor example, if the tab or projection 9 of the tape 3 is formed to function as a stencil, the heat and ircssiire of the calender rolls 26 and 27 will produce an impression of the tab or projection 9 upon the selvage of the material, in which the insignia or other markings on the tab appear in relief. On the'otlier hand, if the marking is to take the form of a decalcoinania transfeigit will be obvious that the transfer may be made'to the material 36 in an equally eflicient manner. Y

lnA order 'that thermoveinent of the ribbon or tape 8, through the guideway 23, may be performed so as to synchronize with the speed of the material 36, in its passage between thel calender rolls 26 and 2T, there may be provided a brake or governor for the rollr or spool 7, Vwhich consists of a weight 48 suspendedr from a strap or other flexible medium 49 detachably Connected at its other end to a pin 50 projecting from ,one side of the housing 13. rlhis strap or flexible medium 49 l dasses over a grooved pulley 51, which is keyed to one endA of the stubV shaft 11, as shown at 52, the weight 48 being of the proper size to retard the rotation of the shaft 1l sufficiently to insure the aforesaid syncl'ironism in movement of the tape 3 and the material v36, without producing such an excessive strain on said tape as to cause injury thereto.
